Objective To investigate the possible mechanism of the gap junctional influence on the change in permeability of the blood-brain barrier(BBB)after reperfusion subsequent to cerebral ischemia.Methods In the test laser scanning confocal microscope(LSCM)was used to investigate the change of Cx43 levels and distribution.The MCAO/R model was induced using intraluminal suture technique first described by Longa with a little modification.A total of 60 Wistar rats were divided into 4 groups:the sham-operation group,control group,octanol-treatment group and DMSO vehicle control group. Control group were further divided into seven subgroups at different time points of reperfusion after middle cerebral artery occlusion.To observe the change in permeability of BBB,Evans blue(EB)in the brain tissue was surveyed by the means of EB fluorescent quantitation.Octanol-treatment group and DMSO vehicle control group were done at the point of the peak of permeability of BBB.Octanol,the specific blocker for gap junctions(GJ)was used in an intervention study.To compare the amount of EB with the same point of groups,the influence of octanol on BBB permeability was investigated.Results At 3 h of reperfusion after cerebral ischemia for 2 h,the permeability of BBB began to increase,reached the peak at 24 h of reperfusion and was still elevated at 72 h.The Cx43 expression formed into bigger plague and remained linear disposition in the penumbra after reperfusion subsequent to cerebral ischemia.Octanol group was done at 24 h of reperfusion after cerebral ischemia.The amount of EB of octanol group((4.924?0.296)?g/g)was significantly lower than that of corresponding operation control group(5.543?0.506)?g/g.Conclusions (1)Cx43 expression is concentrated around vessels in brain.The Cx43 forms into bigger plague and the function maybe strengthens after reperfusion.Gap junction might aggravate the disruption of BBB.(2) Octanol,the specific blocker of gap junctions,could effectively prevent the permeability of BBB from increasing and has a protective effect on BBB.

We observed clinical features of 18 bronchopulmonary dysplasia (BPD) patients who were admitted to the neonatal intensive care unit in the Severance Hospital of Yonsel University College of Medicine from January 1. 1987 to June 30. 1991. Eight patients in whom ventilator settings were unchanged for more than 5 days because of lack of improvement in pulmonary function. The effects of dexamethasone in ventilator-dependent were included in the short-term dexamethasone therapy. 1) Eighteen BPD patients consisted of 15 premature infants (83%), 1 full-term infant, and 2 post-term infants, The mean gestational age of the patients were 30 weeks and the mean birth weight was 1,420gm. And there were 13 male and 5 female infants. 2) The underlying conditions which necessitated ventilatory support support were hyaline membrane disease in 13 patients (72%), apnea in 2 (11%), and meconium aspiration syndrome in 3. There patients with meconium aspiration syndrome were either full-term or post-term infants, of whom 2 had neonatal persistent pulmonary hypertension. 3) The mean age at the start of ventilator care was 8 hours and the mean PIP was 32 cm H2O. The mean duration of ventilator care of oxygen therapy and of high O2 requirement (FiO2>0.8) were 39 days, 75 days and 20 days, respectively. 4) Patent ductus arteriosus developed in 8 patients during mechanical ventilation, but they were all closed with the use of mefenamic acid, There were also 4 cases of pneumothorax, 2 cases of pulmonary parenchymal emphysema, and 1 case each of pneumomediastinum and pneumoperitoneum. 5) The mean gestational age of the dexamethasone-treated group was 30 weeks and the mean birth weight was 1,320gm, The mean age at which dexamethasone therapy was started was 39 days after birth, and in only 3.3 days 6 patients were successfully weaned from ventilator, In 5 cases the first trial of dexamethasone therapy was enough but the rest needed the 2nd trial for ventilator weaning. 6) In 6 BPD patient who were weaned from the ventilator after dexamethasone therapy, there were significant decreases in MAP (11.1 vs 8.0 cmH2O), and FiO2 (0.73 vs 0.61), but a significant increase in the urine output (2.56 vs 3.7ml/kg/hr) for the pretreatment (5 days prior to therapy) versus posttreatment period (first day of therapy). 7) The complications of dexamethasone treatment were transient hypertension and hyperglycemia in 3 patients, and systemic candidiasis and gastrointestinal bleeding in 2 patients who failed to be weaned after dexamethasone therapy. Our results suggest that the short-term dexamethasone therapy in bronchopulmonary dysplasia patients who are dependent on mechanical ventilation enables weaning in a short period of time. The inspiratory oxygen concentration and the mean airway pressure may be decreased and the urine output may be increased from the first day of medication, improves pulmonary function and decreases pulmonary interstitial edema.

Objective To investiagte the serum adiponectin concentration in preeclampsia and its relationship with serum leptin and soluble leptin receptor levels.Method The level of adiponectin,leptin and soluble leptin receptor in serum were measured by enzyme-linked immunosorbent assay(ELISA)in 38 patients with preeclampsia and 42 patients as control.The relationship of free leptin index(leptin/soluble leptin receptor) to preeclampsia was analyzed.Results There were no significant differences in maternal age,gestational age and body mass index(BMI)between two groups.But the gestational age and birth weight were significantly lower in preeclampsia than in control.The patients with preeclampsia had significantly higher levels of serum adiponectin, leptin and free leptin index(1691.7?g/ml,37.5 ng/ml and 0.95 respectively)than the control(689.4?g/ml, 19.3 ag/ml and 0.49,respectively).But there was no significant difference in serum level of soluble leptin receptor between the groups(35.0 ng/ml vs 42.2 ng/ml).Serum adiponectin was not significantly correlated with the level of leptin,soluble leptin receptor and free leptin index.Area of serum adiponectin,leptin and free leptin index in preeclampsia under the ROC curve were less than 0.5.Conclusions The patients with preeclampsia have paradoxical higher serum levels of adiponecfin and more bioavailability of leptin,suggesting these may be important factom of this complication.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.

OBJECTIVE: It is known that normal follicular growth and pregnancy are possible using Follicular stimulating hormon(FSH) alone during controlled ovarian hyperstimulation(COH) for IVF-ET. The purpose of this study was to compare and analize the results of COH for IVF-ET between a group using only FSH-HP and a group using FSH/hMG METHOD: 111 cycle of the total 280 COH for IVF-ET cycles belonged to the FSH-HP group, and the FSH/hMG group accounted for remaining 169 cycles. The amount of gonadotropin administered, the duration of hormonal therapy, the number of embryos transfered, the endometrial thickness, and the pregnancy rate were compared between the two groups and statistically analized using the t-test. p values less than 0.05 deemed statistically significant. RESULT: There were no statistical differences on the amount of gonadotropin administered, the duration of hormone therapy, number of oocytes retrieved, nor the endometrial thickness between the two groups. However,the serum E2 level was significantly lower, and the number of embryos of high quality(GradeIandII) significantly higher in the FSH-HP group. In pregnancy rate, FSH-HP group shows higher than FSH/hMG group(38.8% VS 34.2%). but the difference was not large enough to be considered statistically significant. CONCLUSION: The results of this study show that compared to using FSH/hMG, treatment with FSH-HP alone allowed the retrieval of more embryos of high quality, and although not statistically significant, achieved a higher pregnancy rate, thus indicating that it can be used as an effective method for COH.

Uterine fibroids are the most common benign tumor of the female genital tract. Traditional therapy for symptomatic fibroids has been either myomectomy or hysterectony, depending on whether futhur fertility is desire. A promised new altermative therapy-embolization of the uterine arteries- is now available. A 29 year-old woman was diagnosed of uterine fibroid by ultrasonogram and other techniques. We have experienced one case of uterine fibroid necrosis after transarterial embolization. Now we report a case of uterine artery embolization for treattement of uterine fibriods with a brief review.
